‘I have to tell you something’: How Kim Kardashian shared the news of her pregnancy with sister Kourtney during a terrified midnight emergency

When Kim Kardashian told sister Kourtney she was pregnant, it didn’t come with the fanfare and glamour usually associated with the reality stars.

In the middle of the night, she called her older sister in a panic, as revealed in the teaser for Sunday’s Kourtney & Kim Take Miami.

‘I know you’re mad at me, but can you please get me from Jonathan’s. It’s an emergency,’ the 32-year-old said in the panicked call.

The big reveal: The episode in which Kim Kardashian tells sister Kourtney her baby news airs Sunday night, but the teaser clip shows the very moment when she confessed her pregnancy to her sister

The clip shows Kourtney pulling herself from bed and rushing to relieve her sister from friend Jonathan Cheban’s home, putting aside the fight she had with Kim about her decision to hire a P.I. to determine whether Scott Disick was cheating.

Make-up free, Kim turns to her sister in the car, knowing that she has to divulge something she’d been keeping secret.

‘I have to tell you something, but I don’t want to tell Khloe, but… you’re gonna die,’ the mini-mogul ekes out.

'What is it?': Kourtney Kardashian anxiously awaited the news that had Kim calling her in the middle of the night to take her to the hospital

With child: Kim looked to her sister with concern on her face, as she wanted to avoid telling Khloe as well, and simply said, 'I'm pregnant.'

Concerned, Kourtney asks what it is.

‘I’m pregnant,’ Kim finally reveals.

After confirming her seriousness, she explains what caused her to call her big sis: ‘And I have, like, the worst stomach pain ever.’

In the clip, Kim is only a month pregnant, a vulnerable time during one’s first trimester.

Sigh of relief: The 32-year-old seemed more at ease once she told her older sister what was going on

'Are you serious?': Though there were no squeals of excitement during their ride to the hospital, Kourtney flashed a surprised smile at her sister's news

Aside from telling Kourtney for emergency’s sake, Kim reveals that the only other person who knew of her pregnancy at the time was rapper boyfriend Kanye West.

Thankfully, audiences can rest assured that the Armenian beauty and her baby were just fine, as the reality star posted two pictures of her now six-month baby bump to her Instagram account on Saturday.

Though the curvaceous mom-to-be has been under attack for gaining weight, her Instagram pictures showed her appearing slender in black leggings and a white T-shirt.

Based on the photographs, it’s clear that her pregnancy is mainly adding belly to her tiny 5ft2 frame.
